In the embodiment, the air conditioner 2 is a cooler.
The air conditioning module 21 has a first control unit 212 and at least one blade 211 for controlling the wind direction of the air conditioning module 21. The blade 211 is disposed at an outlet side of the air conditioning module 21. The first control unit 212 can control the blade 211 to rotate, so that the cold air outputted by the cooling apparatus of the air conditioning module 21 can be guided toward the desired direction by the blade 211. In the embodiment, the air conditioning module 21 has a plurality of the blades 211, and the blades 211 can be arranged toward the same direction or different directions.
For example, the wireless access module 22 can be a wireless access point (WAP), but it's not limited. The wireless access module 22 includes at least one antenna 221 and a second control unit 222.
The second control unit 222 and the antenna 221 are electrically connected with each other. The second control unit 222 can feed the signal into the antenna 221 through the coaxial transmission line L, and then the antenna 221 can transmit the signal in the form of electromagnetic wave. In addition, the antenna 221 can transmit the signal in the form of electromagnetic wave to the second control unit 222 through the coaxial transmission line L so as to detect an intensity of the signal received by the antenna 221. The second control unit 222 can be disposed inside or outside the air conditioning module 21. Preferably, the second control unit 222 is disposed inside the air conditioning module 21 for reducing the occupied space. In the embodiment, the first control unit 212 and the second control unit 222 can be disposed separately or integrally on a circuit board.
The antenna 221 is disposed on the blade 211. In the embodiment, the wireless access module 22 has a plurality of antennas 221, which are disposed on the blades 211, respectively. The blade 211 can be the carrier or the substrate of the antenna 221. The antenna 221 and the blade 211 can be connected by adhering, locking, screwing or wedging, but it's not limited. Alternatively, the antenna 221 and the blade 211 can be integrally formed by etching or double injection molding. In the etching method, a metal layer is formed on the blade 211 in advance, and the metal layer is etched to form the desired pattern, which constructs the antenna 221. In the double injection molding method, the antenna 221 is manufactured in advance. Then, the antenna 221 is disposed in a mold, and a non-metal plastic material is injected into the mold. Thus, the blade 211 and the antenna 221 can be formed by double injection molding, so that the blade 211 can be tightly connected to the periphery of the antenna 221.
The combination aspects of the antenna 221 and the blade 211 will be described hereinbelow with reference to FIGS. 3A to 3C. FIG. 3A is a top view of the combination of the antenna 221 and the blade 211. In this case, the antenna 221 is a dipole antenna and has a grounding area G. Of course, the antenna 221 can be a monopole, a planar or a planar inverted-F antenna. In addition, the antenna 221 can be a single-band or a dual-band antenna. The type of antenna 221 is not limited to the above description, and it can be configured depending on the product need. Alternatively, the antenna 221 can be an omni-directional or a directional antenna. In the embodiment, the antenna 221 is preferably a directional antenna.
As shown in FIG. 3B, the antenna 221 is embedded in the blade 211. The blade 211 can be an insulation substrate, such as a ceramic substrate or a resin substrate.

In this case, the blade 211 is a carrier for carrying the antenna 221′.
The function of the air conditioner 2 will be described hereinbelow with reference to FIG. 4. The first control unit 212 and the second control unit 222 are electrically connected with each other. When the blades 211 rotate, the second control unit 222 can detect the intensities of the signals received by the antenna 221 as the blades 211 rotate to different directions. For example, when the blades 211 rotate to a first direction, the second control unit 222 can detect the strongest intensity of the signal. Then, the second control unit 222 transmits a first control signal FS to the first control unit 212. The first control unit 212 controls at least one part of the blades 211 toward the first direction according to the first control signal FS. Accordingly, some directional antennas 221 can face the source of the electromagnetic wave so as to enhance the transmission performance. In addition, the blades 211 can be rotated toward the position of the user, so that the airflow outputted from the air conditioning module 21 can be guided toward the user, thereby increasing the performance of the air conditioner 2.
In addition, the second control unit 222 can detect the intensity of signal in the space to find a secondary intensity at a second direction. Then, the second control unit 222 transmits a second control signal SS to the first control unit 212, and the first control unit 212 can control the other part of the blades 211 toward the second direction according to the second control signal SS. Accordingly, some of the directional antennas 221 can face the source of electromagnetic wave with the secondary intensity so as to further enhance the transmission performance. In addition, some of the blades 211 can be rotated toward the position of the user, so that the airflow outputted from the air conditioning module 21 can be guided toward the user, thereby increasing the performance of the air conditioner 2.
To sum up, the air conditioner of the invention has the antenna disposed on the blade for controlling a wind direction of the air conditioning module. Compared with the prior art, the air conditioner of the invention has the wireless access function due to the wireless access module.
